Great replacement for 75 year old latchset

The quality and workmanship of this latchset/lockset is very good. I purchased it to replace a lockset on a bath in our 75 year old house and it works great. The face plate is thicker than the old lockset so I had to chisel out the recess, which meant the "backset" distance was about an 1/8" more and required enlarging the holes for the knob and thumbturn. I will definitely purchase from Hardwick & Sons again.

Great fit

We purchased this lock set to replace an original mortised set from the 1930s. It was a great fit; only slight rework of the pocket was required. I appreciate the full specs on the site which aided in making sure it would work. I covered the old keyhole on one side with a full length escutcheon plate, and added a thumbturn on the other side. Perfect! I'll be back for additional replacement sets.

Very good product and great customer service

I ordered a mortise lock set for an old 110 year door. The lock was excellent quality but unfortunately was slightly to large for my door. Customer service was outstanding when I contacted them.
